Answer
The intermolecular bonds in ionic compounds are stronger than those present in covalently bonded compounds, resulting in ionic compounds having high melting and boiling points.
Procedure
The positive and negative ions formed during ionic bonding are held together by strong forces of attraction between the oppositely charged ions. These ionic bonds between the charged particles result in a relatively large structure of ions, such as a grain of table salt instead of a single molecule of NaCl. Because the ions are held together tightly in this crystal structure it takes a lot of energy to break all the bonds. As a result, ionic compounds have high melting and boiling points.
In the case of covalent bonds, the molecules are bound together by weaker hydrogen bonds or van der Waals interactions, and the structures are more variable and sometimes fluid, such as the case of water. This bonding causes lower melting and boiling points.
